American classical music is music written in the United States but in the European classical music tradition. In many cases, beginning in the 18th century, it has been influenced by American folk music styles; and from the 20th century to the present day it has often been influenced by folk, jazz, blues, and pop styles.

Jazz music is sometimes referred to as American classical music, mainly by jazz musicians. They feel that, being as jazz originated in America, jazz is the true American classical music.

Sometimes the later Rock & Roll is referred to as American "classic" music, since it too originated in the United States. See also: Rhythm & Blues
